This paper describes the design and construction of a fuel cell hybrid electric vehicle based on the conversion of a five passenger production sedan. The vehicle uses a relatively small fuel cell stack to provide average power demands, and a battery pack to provide peak power demands for varied driving conditions. A model of this vehicle was developed using ADVISOR, an Advanced Vehicle Simulato...

A combined simulation and testing approach has been developed to evaluate battery packs in real driving conditions as opposed to purely experimental testing. The new approach is costeffective, greatly accelerates battery development cycle, and enables innovative battery design and optimization. Several fundamental models for valve-regulated lead-acid (VRLA), nickel-metal hydride (NiMH), and Li-...

Novel technologies such as electric vehicles will have a fundamental impact on the performance of a network and it is important that planners have a tool to accurately assess policies aimed at reducing vehicle fuel consumption and emissions. This work presents a novel framework to estimate city-wide vehicle environmental effects that integrates a dynamic traffic assignment model with a novel ap...

Electric vehicles (EVs) have gained the attention of many authorities, automakers and researchers due to their considerable energy saving and emission reduction. One of the main issues that must be considered in design of a road vehicle is the calculation of aerodynamic forces. This issue also must be scrutinized in the design of EVs. Installation of rear spoiler is one of the solutions propose...

This paper studies the impact of fuel-cell (FC) performance and control strategies on the benefits of hybridization. One of the main weak points of the FC is slow dynamics dominated by a temperature and fuel-delivery system. Although many researchers have investigated the use of different powertrain topologies, component sizes, and control strategies in fuel cell vehicles, a detailed parametric...

The first commercially available plug-in hybrid electric vehicle (PHEV), the General Motors (GM) Volt, was introduced into the market in mid-December 2010. The Volt uses a series-split powertrain architecture, which provides benefits over the series architecture that typically has been considered for use in electric-range extended vehicles (EREVs). A specialized EREV powertrain, called the Volt...
